Joule is a unit of work. Now by using the formula of work done  W = F s(F = force and s = displacement) = Mas    (a = acceleration) = Msv/t   (v = velocity  and t = time) =Ms s/t​2 (as velocity is displacement /time) W = M s2/t2 hence the above formula is in form of its fundamental units like mass, time and length and the dimension formula of joule = ML2T-2
